Image showing a digital wrench as a test tool Lessons Learned in Testing a UI Test Automation Tool

How do you test a tool to be used for automated testing? If a tool executes an automated test that generates keyboard and mouse events to replay user actions, can the test emulate user input and control another instance of the tool to automatically record and play another test? Here's how you test the test tool.

Sinking boat Guaranteed Methods to Ruin Your Test Automation

After working to develop the test automation patterns used by experienced practitioners to solve common test automation issues, Seretta Gamba started to consider what can ruin a test automation effort instead. Here she shares two sure-fire methods that can destroy your test automation. Steer clear of these examples!

Developers and testers having a conversation about behavior-driven development A Conversation about Testing within BDD

People using behavior-driven development (BDD) say conversation is the most important part of the process. They use a “given-when-then” format to describe the current state, an action that is supposed to occur, and what results to expect. But if that structure isn't working for your team, don't restrain discussion.

AI traffic light Testing Artificial Intelligence: How Low Can You Go?

Artificial intelligence (AI) is propelling to the forefront once more. With the growing importance of AI comes the question: How do I test it? AI systems do not necessarily behave predictably. This means that traditional test cases of the form "do this, expect that" are not always sufficient.

Four checkboxes with two of them checked Questions to Ask during Test Selection for Automated Tests

We use test design techniques to answer the questions “What do I need to test?” and “What tests should I perform?” We try to ensure test coverage during test automation too, except that choosing poorly creates slower builds and unreliable information about product quality. Here are some guidelines for test selection.

Pipelines, photo by Bernard Hermant Testing Your DevOps Is Just as Important as Testing Your Software

Many DevOps engineers fail to test their automation code in the same way they test the software they deploy. It's crucial for software to have tests, and this should apply to infrastructure-as-code software too, if we plan to change and improve this code with no worries about breaking automation in our DevOps pipeline.

feedback form Is Shifting Left Forcing Developers to Become Testers?

Even if it’s the testers who are asked to make some of the biggest changes when it comes to the concept of shifting left, they’re rarely the ones who are calling the shots. When it comes to testing earlier and more often during a project, it’s management making the big decisions.
